目的探讨肾盂输尿管连接部梗阻的诊断与治疗方法。方法30例肾盂输尿管连接部梗阻患者,采用尿路造影或磁共振确诊,其中行Anderson-Hynes术26例(27侧),纤维索带松解2例,异位血管切断肾盂复位1例,肾切除1例。结果Anderson-Hynes肾盂成形术均一次成功,单纯行纤维索带松解和异位血管切断者术后发生再梗阻,改行Anderson-Hynes术治愈。结论Anderson-Hynes是治疗肾盂输尿管连接部梗阻的理想方法,术中应用双J管作内引流效果佳,可以减少再狭窄的发生。
Objective To investigate the diagnosis and treatment of ureteropelvic junction obstruction. Methods Thirty ureteropelvic junction obstruction patients were diagnosed by urography or magnetic resonance imaging. Anderson-Hynes procedure was performed in 26 cases (27 sides), in 2 cases with loosening of fibrous cord, in 1 case of ectopic resection of renal pelvis, in renal Excision of 1 case. Results Anderson-Hynes pyeloplasty was successful all at once. Only simple fibrolactone and ectopic vascular resection were followed by re-obstruction. Anderson-Hynes technique was used to cure it. Conclusions Anderson-Hynes is the ideal method for the treatment of ureteropelvic junction obstruction. Intraoperatively, double J-tube drainage is effective in reducing internal restenosis.
